330 Chapter 5: Network Protocols
Scenario 5-2: IP Subnet Design with a Class B Network
Your job is to plan a new network. The topology required includes three sites, one Ethernet at
each site, and point-to-point serial links for connectivity, as shown in Figure 5-44. The network
may grow to need at most 100 subnets, with 200 hosts per subnet maximum. Use network
172.16.0.0. Use Table 5-46 to record your choices, or use a separate piece of paper.
